Loud or excessive snoring can also be a symptom of obstructive sleep apnea. This medical condition can cause you to stop breathing while sleeping due to an obstruction or blockage in the throat or airway.
People with sleep apnea may snore loudly or make choking sounds as they try to breathe. This may be caused by the tongue dropping into the back of the throat or by the throat collapsing during sleep.
When the airway is blocked, too little oxygen gets into the blood and the sleeper wakes up to breathe. This can happen a few times or hundreds of times each night, leading to very fragmented sleep.
4) Circadian rhythm disorders
Circadian rhythm disorders can throw the normal pattern of sleeping and waking out of alignment in several different ways.
Some people have a delayed pattern that makes them want to go to sleep at least two hours later than normal and wake later in the morning. Others want to sleep before a normal bedtime and wake up very early in the morning.
People with an irregular sleep pattern may nap at irregular intervals throughout the 24-hour day, without a set or recurring schedule of sleep.
Jet lag is a type of circadian rhythm disorder that happens when you cross multiple time zones, which forces your sleep and wake schedules to change.
This type of sleep disorder may cause you to have abnormal movements, activities or dreams. You may appear to others to be awake during these episodes, even though you are actually asleep.
Sleep hallucinations may make you believe you are experiencing something that is not actually real, while exploding head syndrome can make you hear a loud, imaginary sound like a bomb exploding or a loud bang as you are falling asleep or waking up.
Other parasomnias may cause you to walk, talk or even eat while you are asleep, or may cause nightmares or night terrors that leave an intense feeling of fear when you wake up.
6) Sleep movement disorders
Restless legs syndrome is the most commonly known sleep movement disorder.
